“…It also resembles two other species of small Chlorella that have been previously described, one from the northern Adriatic sea (Andreoli et al 1978), the other, a freshwater species, from Lake Pupuke, New Zealand (Dempsey et al 1980). Such small eukaryotic algae, themselves scarcely larger than some mitochondria, must have structural and physiological features worth investigating.…”

The ultrastructure, growth requirements, pigment composition and photosynthetic characteristics are described for a small eukaryotic alga (mean diameter 2.25 ± 0.41 μιτι) isolated from the waters of a coral reef. It is provisionally identified as Chlorella nana Andreoli, Rascio et Casadora. It grows rapidly in culture (over two divisions per day) and has a requirement for thiamine and vitamin B12-It is particularly suited to grow at low light intensities and has a high maximum photosynthetic efficiency (6.93 -8.30 μg C μg chl a~*h~]) with over 30% of the early products of photosynthesis appearing in the protein fraction.

“…Since it had been shown previously (Soeder, 1964;Atkinson, Gunning & John, 1972;Yamada & Sakaguchi, 1982; see also Dempsey, Lawrence & Cassie, 1980;Rascio, Casadoro & Andreoli, 1980a, b;Rascio & ~s~doro, 1981;Lec et al, 1982) that the ultrastructural appearance of cell walls of Chlorella spp. can vary in different species, this feature was also examined in symbiotic ChloreIIa.…”

“…The trilaminar appearance, particularly during the formation of new cell wall, was asymmetric, with the outer layer more dense than the inner. Dempsey et al (1980) reported a trilaminar sporopollenin layer in Chlorella minutissima 10-15 nm wide and symmetrical in appearance. Rascio et al (1979) revealed a tri-laminar layer in Chlorella nana 17 nm thick and with a reverse asymmetry, the inner layer appearing denser than the outer.…”

Ultrastructure and Taxonomic Observations on Marine Isolates of the Genus Nannochloris (Chlorophyceae)

The chlorophycean genus Nannochloris has historically been distinguished on the basis of two morphological properties: division into two and only two daughter cells, and absence of a surrounding mother cell wall during cell division. Our ultrastructural examination of five strains of Nannochloris frequently revealed multiple fission of cells and the presence of a mother cell wall. In several strains, the trilaminar structure of the cell wall was indicative of the presence of sporopollenin. On the basis of ultrastructural examination alone, these Nannochloris strains could not be distinguished from several known minute species ofChlorella, and the validity of Nannochloris äs a distinct genus tnust be questioned. However, reclassification of the genus is not recommended until further work on the biochemical taxonomy of Nannochloris is undertaken.
